Here are the Notes on EMP and Related Subjects edited by Dr. Carl E. Baum. These were started in 1964 by Dr. Ralph Partridge of Los Alamos Scientific Laboratory with the first several of the Sensor and Simulation Notes. This was begun as a means of rapid communication between workers in the EMP (Nuclear Electromagnetic Pulse) community in the United States and Britain. As such it can be considered as some kind of informal journal of the EMP community.
A Note may be very brief (a few pages) or quite lengthy (over 100 pages), giving a new idea, an analysis of an old problem, or whatever. The essence is informality and speed of communication.
Noting that Lieutenant Carl E. Baum of the Air Force Weapons Laboratory was writing the largest number of Notes, Dr. Partridge turned the editorship over to him after just a few years. Since the beginning the Notes have expanded to many more series as can be seen here. The number of Notes is approaching 2,000.
Over the years various series were added after the Sensor and Simulation Notes (Theoretical Notes, Interaction Notes, etc.). This reflects the expansion of the technology into various related areas. As one can see, the various series can be grouped into larger sets as EMP, ACT 
(Analytical and Computational Techniques), PEP (Pulsed Electrical Power), etc.
In 1978 EMP effectively went public with the publication of the Joint Special Issue on the Nuclear Electromagnetic Pulse (IEEE Trans. Antennas and Propagation, January 1978; IEEE Tran. EMC, February 1978). As one can see there, numerous Notes are referenced. Over time many more scientists and engineers have participated in the Notes and they are currently available all over the world. Even EMP has been generalized to include what are called High-Power Electromagnetics (EM pulse radiators, interaction and effects) and Intentional Electromagnetic Interference (IEMI). Every so often publications appear in the regular journals and books to summarize and update the technology with numerous Note references. See (besides the EMP Special Issue) some of the more important ones:

Dr. Baum retired in 2005 from the Air Force Research Laboratory and is now a Distinguished Research Professor at UNM. As such, the Notes are now edited and distributed out of UNM. We would like to thank William D. Prather and Judy Johnston of AFRL for their assistance in getting many of the old notes cleared for public release and contained here. While many Notes are not currently releasable, much of their contents have appeared in open publications. It would be good if more of these were eventually released so as to clarify the historical record.
So, happy hunting through the Notes! We are in the process of getting all the public Notes onto this site, so you may want to bookmark this page for return trips.
